Answer:
Carbonates (CO3-2), phosphates (PO4-3) and sulfides (S-2) are insoluble.
The exceptions are the alkali metals and the ammonium ion.
The correct answer is :
the purpose of heating the mixture is to accelerate the reaction and mix the reagent.
The explanation:
Many organic reactions are slow and can take an extended period of time to achieve any noticeable effect so heating is often used to increase the rate of reaction. However, many organic compounds have low boiling points and will vaporise upon exposure to such high heat, preventing the reaction from proceeding in full.
so, heating is used. This refers to heating a solution with an attached condenser to prevent reagents from escaping
Scientific law is based on answers that are a result of experimentation, number of repetitive tests (to ensure credible results), and observations about Earth's atmosphere and it's life
Legal law is based from morale and principle high ground that are designed to bring order through an armed force. If you look at it very carefully, it's designed to control human nature, savagery, and instinctual behaviour. How so? Without order, everything morphs into chaos as people have the liberty to fight, kill, and steal without penalization.
